3 Claims.

This invention appertains to toilet bowls and has for one of its primary objects the provision of novel means for withdrawing all objectionable odors from the bowl when the same is in use.

Another salient object of my invention is the provision of means incorporated directly within the bowl and operated by the weight of a person for carrying all foul air from the bowl, said means embodying an electrically driven exhaust fan housed within a part of the bowl.

A further important object of my invention is the provision of novel means for closing the circuit through the motor upon the rocking of the toilet bowl seat incident to the weight of a person thereon, novel means being provided and actuated by the toilet seat bowl for closing the air inlet port of the fan when the bowl is not in use, whereby the back flow of objectionable odors into the bowl will be prevented.

A further object of my invention is the provision of novel means for incorporating the motor. fan, and control mechanism within a part of the bowl whereby all objectionable protruding parts will be eliminated, thereby permitting a pleasing and symmetrical appearance to be given to the bowl.

A still further object of my invention is to provide means for exhausting foul odor from a toilet bowl of the above character, which will be durable and elficient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawings, in which drawings:-

Figure l is a side elevation of a toilet bowl constructed in accordance with my invention, parts of the same being shown broken away and in section, the view also illustrating the novel trap utilized in connection with the exhausting of the foul air.

Figure 2 is a horizontal section through the bowl taken on the line 2-2 of Figure 1 looking in the direction of the arrows.

Figure 3 is a rear elevation of a toilet bowl constructed in accordance with my invention showing parts thereof broken away and in section.

Figure 4 is a fragmentary section through the bowl taken on the line 44 of Figure 3 looking in the direction of the arrows showing parts of the mechanismin their inoperative position.

Figure 5 is a view similar to Figure 4 showing parts in their operative position.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A generally indicates my improved toilet (Cl. 42l3) bowl which. comprises any preferred type of water receptacle 10 having formed therein the water trap 11 which communicates with the waste pipe 12 through the medium of the passageway 13 formed in said bowl. The water receptacle 10 is supported by a suitable hollow base 14 which can be of ornamental appearance. The upper end of the water receptacle 10 is provided with a hollow rim 15, which, in accordance with my invention, is divided circumferentially by a circumferentially extending partition wall 16, forming the flush chamber 17 and the air chamber 18. The flush chamber 17 has communicating therewith the water outlet ports 19, while the air chamber 18 has formed therein air intake ports 20.

The rear of the bowl has formed therein in back of the water receptacle 10 air passageways 21 which lead on opposite sides of the water inlet flush pipe 22. The base also has formed therein adjacent to the lower end thereof a cylindrical chamber 23, one end of which can be closed by a removable plate 24, preferably formed from the same material as the bowl. The opposite wall of the cylindrical chamber 23 can be provided with a removable hand plug 25, for a purpose, which will be later described.

The chamber 23 receives an electric motor 26 of the desired rating, which motor can be placed in the chamber upon the removal of the plate 24. The removable plug 25 can be removed to facilitate the oiling of the motor when necessary or desirable. Arranged at one side of the electric motor 26 is a suction fan 28, embodying a casing 29 having an axial air inlet port 30 and a peripherial outlet port 30'. Connected with the fan casing 29 is an air entrance chamber 31 having an air inlet port 32 which communicates with the air passageways 21 heretofore referred to. The air inlet port 32 of the air casing 31 can be closed by a swinging gate 33, which is operated by the raising and lowering of the toilet bowl seat 35. As in the usual construction the toilet seat cover 34 fits over the toilet seat 35 and the cover 34 is rotatably mounted on a shaft 40. This shaft 40 has secured thereto by means of brackets 36 the toilet seat 35. The shaft 40 is rockably mounted in bearings 37 anchored in the upper face of the rim 15 at the rear end thereof.

From the construction so far, it can be seen that upon the raising of the seat cover 34 that no movement is imparted to the shaft 40 but that the shaft 40 will be caused to rock when weight or pressure is applied to the forward end of the seat 35. Rigidly secured to the shaft 40 for rocking movement therewith is the depending operating arm 38 which extends into the air passageway 21 of the bowl, the lower end of the arm 38 has pivotally connected thereto a link 39, which is in turn connected with the swinging gate 33 for the air inlet opening 32 of the air casing 31. When weight is applied to the seat 35 the shaft 40 will rock and swing the arm 38 rearwardly causing the straightening out of the link 39 and the consequent opening of the gate 33 to permit the entrance of air into the casing 31. A spring 41 is employed for normally pulling down on the arm 38 for causing the return of the seat 35 to its normal position when the weight is removed therefrom. Thus immediately upon the rising of a person the arm 38 will be returned to its normal position and the gate 33 will be moved to close the opening 32 and thus prevent the inflow of any objectionable odors.

Referring to the fan 28 and the motor 26, the fan 28 includes the impeller 42 which is secured to the armature shaft 43 of the motor 26. This impeller is arranged within the casing 29 as shown and upon the closing of the circuit through the motor the impeller functions to suck in air through the axial opening 30 and to expel air through the outlet opening 30'.

The outlet opening 30' communicates with an outlet passageway 44 formed in the base of the bowl which in turn communicates with a foul air lead-off pipe 45 which can be extended to any desired place. I have incorporated in the pipe 45 a trap 46 which forms animportant part of my invention.

The trap 46 not only communicates with the lead-off pipe 45 but also with the waste pipe 12 and it is obvious that any moisture carried off with the foul air will be caught by the trap 46. When the trap becomes full of water the same will drain into the waste pipe 12.

I have also provided a novel means for opening and closing the circuit through the motor 26 and this means is also actuated by weight on the seat 35 through the medium of the arm 38. Arranged within the base of the bowl is any preferred type of switch mechanism 50 which may include a swinging switch lever 51. This swing ing switch lever 51 is received between laterally extending guide fingers 52 formed or carried by the arm 38. When the switch lever 51 is in its lowered position as shown in Figure 4 the circuit through the motor is opened and when the switch lever 51 is in its raised position, as shown in Figure 5 of the drawings, the circuit through the motor is closed.

When the shaft 40 is rocked by the weight of a person on the seat 35 the rearward swinging movement of the arm 38 will cause the upward swinging of the switch lever 51 through the medium of the pins 52 thus closing the circuit through the motor and allowing the fan to be brought into operation. The fan will create a suction in the air box 31, air passageways 21, air chamber 18 and air intake ports 20. This will efiectively carry off all objectionable odors from the bowl.

From the foregoing description, it can be seen that I have provided a toilet bowl having incorporated directly therein and forming a part there of means for carrying 011 all objectionable odors therefrom and means for preventing the return of objectionable odors into the same.

Changes in details may be made without departing from the spirit or the scope of this invention.
